Implementing Application Layer Protocols for Cisco Networks from Pluralsight

Keep your network running and help your business run more effectively. In this course, you will examine fundamental application layer protocols an their operation including, HTTP, FTP, DNS, DHCP, NTP, and Syslog.

In a business, the entire purpose of the data network is to make the business function more effectively through the use of software applications. In this course, Implementing Application Layer Protocols for Cisco Networks, you will examine critical application layer protocols that help keep the network running, as well as allow end users to easily access resources on the internal network as well as the Internet. Then, you'll learn about the application layer protocols that assist engineers in maintaining the function of a network efficiently, like DHCP, DNS, Syslog, and NTP. Engineers use these protocols to maintain networks, and create an effective user experience. Finally, you'll learn about the other application layer protocols, like HTTP and FTP, and how they are used by the users themselves to browse to websites or download files. By the end of this course, you will have the foundational knowledge of DHCP, DNS, FTP, HTTP, NTP, and Syslog. You will even learn how to investigate a strategy to mitigate rouge DHCP servers from attacking your network.
